Application filed najmh 19, 1931, sent-ii No. 523,777,;1111 in Switzerland. 1min 31, 1930;

This invention relates to water cooled internal combustion engine cylinders and has for its object to provide a simple and improved construction having means whereby 5 solid matter precipitated from the water can be removed.

According to this invention the acket for the cooling Water in addition to havingan outlet opening towards its upper end is provided with a discharge port or conduit leading from the lowest point of the jacket, for the purpose of discharging therefrom solid matter precipitated from the cooling water, so that undue accumulation of deposits which would tend to impair efiicient cooling can be prevented.

One construction according to the invention is illustrated by way of example in the accompanying drawing as applied to 1 a 2 double acting engine cylinder. In the construction illustrated the cylinder comprises a liner a, cylinder heads d and an outer wall I) so constructed as to provide a chamber 7 or water jacket 0 for the cooling -water.,

The water is supplied to the jacket 0 through pipes e and f and is discharged therefrom through an outlet 9 at the upper end of the jacket. In accordance with the present invention a discharge conduit h is provided communicating with the lowest point of the cooling jacket 0 so that solid matter precipitated from the cooling water can be discharged and the accumulation of solid matter which would otherwise impair effective cooling is thus prevented.

I claim:

the lower part of the cylinder another inlet ,for the water, and a discharge port at the lowest point of the, jacket for continuouslyclischarging therethrough, by the coolingcirculation, the slurry continuously forming, 55

and a conduit connected to the discharge port for continuously entraining away the slurry forced thereinto by the circulation.

In testimony whereof I have afiixed my signature. 60
